Direct Observation of the Chemical Transformations in BiVO4 Photoanodes upon Prolonged Light-Aging Treatments
Arcas, Ramón; Cardenas-Morcoso, Drialys; Spadaro, Maria Chiara; García-Tecedor, Miguel; Mesa, Camilo A.; Arbiol, Jordi; Fabregat-Santiago, Francisco; Giménez Juliá, Sixto; Mas, Elena Wiley (2022-03-11)Exposing BiVO4 photoanodes to light-aging treatments is known to produce a significant photocurrent enhancement. Until now, the interpretation given to this phenomenon is associated to the formation of oxygen vacancies and ... -
Highly Durable Nanoporous Cu2–xS Films for Efficient Hydrogen Evolution Electrocatalysis under Mild pH Conditions
Fernandez-Climent, Roser; Redondo, Jesús; García-Tecedor, Miguel; Spadaro, Maria Chiara; Li, Junnan; Chartrand, Daniel; Schiller, Frederik; Pazos, Jhon; Hurtado, Mikel F.; de la Peña O'Shea, Víctor Antonio; Kornienko, Nikolay; Arbiol, Jordi; Barja, Sara; Mesa, Camilo A.; Giménez Juliá, Sixto American Chemical Society (2023-08-04)Copper-based hydrogen evolution electrocatalysts are promising materials to scale-up hydrogen production due to their reported high current densities; however, electrode durability remains a challenge. Here, we report a ... -
Sustainable oxygen evolution electrocatalysis in aqueous 1 M H2SO4 with earth abundant nanostructured Co3O4
Yu, Jiahao; Garcés Pineda, Felipe Andrés; González-Cobos, Jesús; Peña-Díaz, Marina; Rogero, Celia; Giménez Juliá, Sixto; Spadaro, Maria Chiara; Arbiol, Jordi; Barja, Sara; Galan-Mascaros, Jose Ramon Nature Research (2022-07-27)Earth-abundant electrocatalysts for the oxygen evolution reaction (OER) able to work in acidic working conditions are elusive. While many first-row transition metal oxides are competitive in alkaline media, most of them ...
